Key Benefits of Yves Saint Laurent Top Secrets Moisturizing Prep Lotion

 
These are the key benefits you can expect from using Yves Saint Laurent Top Secrets Moisturizing Prep Lotion:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Yves Saint Laurent Top Secrets Moisturizing Prep Lotion is quite moisturizing, with a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈9.0%), Glycerin (est. ≈6.0%) and Butylene Glycol (est. ≈4.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Things to Be Aware Of: Yves Saint Laurent Top Secrets Moisturizing Prep Lotion

 
CreamScan AI identified a few things to consider before adding Yves Saint Laurent Top Secrets Moisturizing Prep Lotion to your skincare routine:
 

Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Yves Saint Laurent Top Secrets Moisturizing Prep Lotion is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Adenosine, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Adenosine provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically exclude the possibility that Adenosine may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were accessible to the CreamScan team at the time of publication.

Therefore, this ingredient does not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Ingredients explained

Water
Est. %65
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Propanediol
Est. %9
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Glycerin
Est. %6
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Butylene Glycol
Est. %4
Function
Origin
Butylene Glycol

A clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.

Dipropylene Glycol
Est. %3
Function
Origin
Dipropylene GlycolA clear, colorless liquid that has several uses. One of its main functions is as a solvent. Dipropylene glycol is also used to reduce the thickness of skincare products.
Bis-PEG-18 Methyl Ether Dimethyl Silane
Est. %2.5
Function
Origin
Bis-PEG-18 Methyl Ether Dimethyl SilaneA silicone with the unusual trait of being able to disperse in water. It moisturizes the skin as a humectant and leaves a soft and smooth after-feel. This ingredient also has foam-boosting properties.
Phenoxyethanol
Est. %1
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin

Chlorphenesin
Est. %0.3
Function
Origin
ChlorphenesinA preservative and broad-spectrum antimicrobial agent that protects products from a wide range of bacteria and fungi.
Disodium Cocoyl Glutamate
Est. %0.3
Function
Origin
Disodium Cocoyl GlutamateA naturally-derived surfactant with gentle cleansing and some foaming ability.
Sodium Citrate
Est. %0.3
Function
Origin
Sodium CitrateA salt of citric acid that has a salty and tart flavor and is used as a fragrance. It is mildly basic, meaning that its addition to a skincare product can adjust the pH upward.
Adenosine
Est. %0.3
Function
Origin
Adenosine

A key molecule responsible for energy transportation, signaling, and enzyme activity. Adenosine is a popular anti-wrinkle ingredient, however, the key study about its anti-wrinkle efficacy (1) does not meet CreamScan Research Evaluation Standards as it is not double-blind.

Est. %0.3
Function
Origin
PEG-240/HDI Copolymer Bis-Decyltetradeceth-20 Ether
Sodium Cocoyl Glycinate
Est. %0.3
Function
Origin
Sodium Cocoyl GlycinateSodium cocoyl glycinate is a cleansing agent derived from coconut fatty acid and glycine, which is an amino acid. It is a mild surfactant, meaning it gently removes oil and dirt particles from the skin leaving it feeling clean but still lathered. It's also responsible for a creamy afterfeel of a product.
Sodium Cocoyl Glutamate
Est. %0.3
Function
Origin
Sodium Cocoyl GlutamateA very effective yet mild cleansing ingredient derived from coconut oil.
Citric Acid
Est. %0.3
Function
Origin
Citric AcidA gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Potassium Hydroxide
Est. %0.3
Function
Origin
Potassium HydroxideA very alkaline ingredient, meaning that it has a high pH. Potassium hydroxide is therefore useful in bringing a low pH in a cosmetic product up to a more neutral, skin-safe level.
Linalool
Est. %0.3
Function
Origin
LinaloolA fragrant, volatile compound naturally present in many essential oils. It has a pleasant scent and is often used in skincare products as a fragrance. People with sensitive skin should try to avoid it, or at least do a patch test before using it.
Salicylic Acid
Est. %0.3
Function
Origin

Benzyl Alcohol
Est. %0.3
Function
Origin

Sodium Hyaluronate
Est. %0.3
Function
Origin
Sodium Hyaluronate

A sodium salt of famous hyaluronic acid. A potent humectant that hydrates the skin, supports collagen function, and fills out small wrinkles. Sodium hyaluronate also offers soothing and antioxidant properties.
